I have been busy this week so had not seen this but
basically anything on the CMSNL site should be available from uk yam dealers, all those mentioned are good , Dave at Yambits , and Yuniparts are good for pattern stuff ,
there is also a DT forum set up and running by a couple of guys i know from the RDforum , http://yamahadtclub.proboards.com/
and Wild Foamy on the Yamaha club forum has a bit of experience with DT 50,s http://yamahaclub.com/forums/
Oh and you can order gen spares from Wemoto if you know the part number , on the right hand side of the home page half way down is a box that says search for OEM part but you will possibly need to add an extra -00 to part numbers , if the search comes up as not found when you enter 1A0-14612-01 (for example) then amend that to 1A0-14612-01-00 and it should work , it will tell you if it is discontinued
